This application claims the benefit of previously filed U.S. Provisional Patent Application entitled “RF LOCAL AREA NETWORK ANTENNA DESIGN,” assigned U.S. Ser. No. 60/845,061, filed Sep. 15, 2006, and which is hereby incorporated herein by reference in its entirety for all purposes.
The present technology relates to utility meters. More particularly, the present technology relates to an aperture coupled patch antenna design for incorporation within meters within an open operational framework employing a radio frequency local area network (RF LAN).
The general object of metrology is to monitor one or more selected physical phenomena to permit a record of monitored events. Such basic purpose of metrology can be applied to a variety of metering devices used in a number of contexts. One broad area of measurement relates, for example, to utility meters. Such role may also specifically include, in such context, the monitoring of the consumption or production of a variety of forms of energy or other commodities, for example, including but not limited to, electricity, water, gas, or oil.
More particularly concerning electricity meters, mechanical forms of registers have been historically used for outputting accumulated electricity consumption data. Such an approach provided a relatively dependable field device, especially for the basic or relatively lower level task of simply monitoring accumulated kilowatt-hour consumption.
The foregoing basic mechanical form of register was typically limited in its mode of output, so that only a very basic or lower level metrology function was achieved. Subsequently, electronic forms of metrology devices began to be introduced, to permit relatively higher levels of monitoring, involving different forms and modes of data.
In the context of electricity meters specifically, for a variety of management and billing purposes, it became desirable to obtain usage data beyond the basic kilowatt-hour consumption readings available with many electricity meters. For example, additional desired data included rate of electricity consumption, or date and time of consumption (so-called “time of use” data). Solid state devices provided on printed circuit boards, for example, utilizing programmable integrated circuit components, have provided effective tools for implementing many of such higher level monitoring functions desired in the electricity meter context.
In addition to the beneficial introduction of electronic forms of metrology, a variety of electronic registers have been introduced with certain advantages. Still further, other forms of data output have been introduced and are beneficial for certain applications, including wired transmissions, data output via radio frequency transmission, pulse output of data, and telephone line connection via such as modems or cellular linkups.
The advent of such variety and alternatives has often required utility companies to make choices about which technologies to utilize. Such choices have from time to time been made based on philosophical points and preferences and/or based on practical points such as, training and familiarity of field personnel with specific designs.
Another aspect of the progression of technology in such area of metrology is that various retrofit arrangements have been instituted. For example, some attempts have been made to provide basic metering devices with selected more advanced features without having to completely change or replace the basic meter in the field. For example, attempts have been made to outfit a basically mechanical metering device with electronic output of data, such as for facilitating radio telemetry linkages.
Another aspect of the electricity meter industry is that utility companies have large-scale requirements, sometimes involving literally hundreds of thousands of individual meter installations, or data points. Implementing incremental changes in technology, such as retrofitting new features into existing equipment, or attempting to implement changes to basic components which make various components not interchangeable with other configurations already in the field, can generate considerable industry problems.
Electricity meters typically include input circuitry for receiving voltage and current signals at the electrical service. Input circuitry of whatever type or specific design for receiving the electrical service current signals is referred to herein generally as current acquisition circuitry, while input circuitry of whatever type or design for receiving the electrical service voltage signals is referred to herein generally as voltage acquisition circuitry.
Electricity meter input circuitry may be provided with capabilities of monitoring one or more phases, depending on whether monitoring is to be provided in a single or multiphase environment. Moreover, it is desirable that selectively configurable circuitry may be provided so as to enable the provision of new, alternative or upgraded services or processing capabilities within an existing metering device. Such variations in desired monitoring environments or capabilities, however, lead to the requirement that a number of different metrology configurations be devised to accommodate the number of phases required or desired to be monitored or to provide alternative, additional or upgraded processing capability within a utility meter.
More recently a new ANSI protocol, ANSI C12.22, is being developed that may be used to permit open protocol communications among metrology devices from various manufacturers. C12.22 is the designation of the latest subclass of the ANSI C12.xx family of Meter Communication and Data standards presently under development. Presently defined standards include ANSI C12.18 relating to protocol specifications for Type 2 optical ports; ANSI C12.19 relating to Utility industry Meter Data Table definitions; and ANSI C12.21 relating to Plain Old Telephone Service (POTS) transport of C12.19 Data Tables definition. It should be appreciated that while the remainder of the present discussion may describe C12.22 as a standard protocol, that, at least at the time of filing the present application, such protocol is still being developed so that the present disclosure is actually intended to describe an open protocol that may be used as a communications protocol for networked metrology and is referred to for discussion purposes as the C12.22 standard or C12.22 protocol.
C12.22 is an application layer protocol that provides for the transport of C12.19 data tables over any network medium. Current standards for the C12.22 protocol include: authentication and encryption features; addressing methodology providing unique identifiers for corporate, communication, and end device entities; self describing data models; and message routing over heterogeneous networks.
Much as HTTP protocol provides for a common application layer for web browsers, C12.22 provides for a common application layer for metering devices. Benefits of using such a standard include the provision of: a methodology for both session and session-less communications; common data encryption and security; a common addressing mechanism for use over both proprietary and non-proprietary network mediums; interoperability among metering devices within a common communication environment; system integration with third-party devices through common interfaces and gateway abstraction; both 2-way and 1-way communications with end devices; and enhanced security, reliability and speed for transferring meter data over heterogeneous networks.
To understand why utilities are keenly interested in open protocol communications; consider the process and ease of sending e-mails from a laptop computer or a smart phone. Internet providers depend on the use of open protocols to provide e-mail service. E-mails are sent and received as long as e-mail addresses are valid, mailboxes are not full, and communication paths are functional. Most e-mail users have the option of choosing among several Internet providers and several technologies, from dial-up to cellular to broadband, depending mostly on the cost, speed, and mobility. The e-mail addresses are in a common format, and the protocols call for the e-mail to be carried by communication carriers without changing the e-mail. The open protocol laid out in the ANSI C.12.22 standard provides the same opportunity for meter communications over networks.
In addition, the desire for increased communications capabilities as well as other considerations including, but not limited to, a desire to provide improved radio frequency transmission range for individual metrology components in an open operational framework, leads to requirements for improved antenna components for metrology devices including meters installed in such systems.
As such, it is desired to provide an improved antenna for coupling utility meters by radio frequency signals to other system components in an open operational framework.
While various aspects and alternative embodiments of antenna configurations may be known in the field of utility metering, no one design has emerged that generally encompasses the above-referenced characteristics and other desirable features associated with utility metering technology as herein presented.
In view of the recognized features encountered in the prior art and addressed by the present subject matter, an improved radio frequency antenna configuration for incorporation within a metrology device for use in an open operational framework has been provided.
In an exemplary arrangement, an antenna has been provided to permit transmission of information between a utility meter and an operational application through a network.
In one of its simpler forms, the present technology provides a patch antenna structure to permit omni-directional transmission of radio frequency signals between a local area network and a meter installed within the service area of the local area network of a utilities service provider.
One positive aspect of the antenna is that it provides an improved, protected mounting arrangement “under the glass” of a utility meter.
Another positive aspect of this type of antenna is that simplified construction techniques may be employed to produce conductive elements for the antenna.
Yet another positive aspect of the antenna is that it isolates non-radio frequency circuitry for the electromagnetic field generated by the antenna.
One exemplary present embodiment relates to an improved antenna for mounting under the glass of utility meters for coupling thereof by radio frequency signals to other system components in an open operational framework. Such antenna preferably may comprise an insulating substrate and first and second conductive layers. More preferably, such insulating substrate may have major front and rear surfaces, and respective lateral ends. At the same time, such first conductive layer preferably may be secured on the rear surface of such substrate, and may define a slot shaped opening therein, with such first conductive layer except for the slot shaped opening thereof covering substantially the entire rear surface of such substrate. Also, such second conductive layer may preferably be secured on the front surface of such substrate, and preferably may cover substantially equally portions of such substrate from the slot shaped opening of such first conductive layer toward the lateral ends of such substrate but short of such lateral ends so as to leave predetermined substantially equal area substrate portions left uncovered on such substrate front surface.
Still further present alternatives to such exemplary embodiment may involve the inclusion of additional features, for example, such as providing such insulating substrate as generally arc-shaped; and such providing such first conductive layer as a conductive ground plane element for such antenna, configured for facing the electronics of an associated utility meter, while such second conductive layer comprises a radiating element of such antenna. With such structure in combination with a utility meter associated non-radio frequency electronics of such utility meter are preferably isolated from an electromagnetic field generated by such antenna while permitting omni-directional transmission of radio frequency signals via such antenna to other system components in an open operational framework.
Other present exemplary embodiments more directly relate to a meter with an under the glass antenna for use with an open operational framework employing a radio frequency local area network. Such a meter may preferably comprise a metrology printed circuit board including components relating to the collection and display of metrology information; radio transmission components received on such circuit board; a microstrip feedline connected with such radio transmission components and received on the circuit board; and an antenna secured to the printed circuit board for support thereof, and electrically grounded thereto. In the foregoing exemplary embodiment, preferably such antenna may include an insulating substrate, with respective first and second conductive layers on opposite surfaces of such substrate, and with such antenna positioned relative to the circuit board and the microstrip feedline received thereon for inductive coupling therewith.
It is to be understood that the present subject matter equally relates to various present methodologies. One exemplary such present embodiment relates to methodology for providing a patch antenna for mounting under the glass of utility meters for coupling thereof by radio frequency signals to other system components in an open operational framework. Such exemplary methodology may comprise providing an insulating substrate having major front and rear surfaces, and respective lateral ends; securing a first conductive layer on such rear surface of the substrate, covering substantially the entire rear surface of such substrate except for a slot shaped opening defined in such first conductive layer; and securing a second conductive layer on such front surface of the substrate, such that substantially equal portions of such substrate are covered from the slot shaped opening of such first conductive layer toward the lateral ends of such substrate but short of such lateral ends so as to leave predetermined substantially equal area substrate portions left uncovered on the substrate front surface.
Other exemplary present methodology relates to methodology for providing a meter with an under the glass antenna for use with an open operational framework employing a radio frequency local area network. Such present exemplary methodology may comprise providing a metrology printed circuit board having thereon components relating to the collection and display of metrology information; providing radio transmission components on such circuit board; supporting on such circuit board a microstrip feedline connected with such radio transmission components; providing an antenna including an insulating substrate, and respective first and second conductive layers on opposite surfaces of such substrate; and securing the antenna to the printed circuit board for support thereof, and electrically grounded thereto, and with such antenna positioned relative to the circuit board and the microstrip feedline received thereon for inductive coupling therewith. It is to be understood of all the present exemplary methodologies that other present methodologies may be provided by various inclusions of other exemplary method features otherwise disclosed herein, each such variations constituting further present methodologies.

Reference will now be made in detail to the presently preferred embodiments of the subject antenna. Referring now to the drawings, and referring first to
Advanced Metering System (AMS) 500 is designed to be a comprehensive system for providing advanced metering information and applications to utilities. AMS 500 is build around industry standard protocols and transports, and is designed to work with standards compliant components from third parties.
Major components of AMS 500 include meters 542, 544, 546, 548, 552, 554, 556, 558; one or more radio networks including RF local area network (RF LAN) 562 and accompanying Radio Relay 572 and power line communications neighborhood area network (PLC NAN) 564 and accompanying PLC Relay 574; an IP based Public Backhaul 580; and a Collection Engine 590. Other components within AMS 500 include a utility LAN 592 and firewall 594 through which communications signals to and from Collection Engine 590 may be transported from and to meters 542, 544, 546, 548, 552, 554, 556, 558 or other devices including, but not limited to, Radio Relay 572 and PLC Relay 574.
AMS 500 is configured to be transportation agnostic or transparent; such that meters 542, 544, 546, 548, 552, 554, 556, 558 may be interrogated using Collection Engine 590 regardless of what network infrastructure lay in between. Moreover, due to this transparency, the meters may also respond to Collection Engine 590 in the same manner.
As illustrated in
In accordance with the present subject matter, the disparate and asymmetrical network substrates may be accommodated by way of a native network interface having the capability to plug in different low level transport layers using .NET interfaces. In accordance with an exemplary configuration, Transmission Control Protocol/Internet Protocol (TCP/IP) may be employed and may involve the use of radio frequency transmission as through RF LAN 562 via Radio Relay 572 to transport such TCP/IP communications. It should be appreciated that TCP/IP is not the only such low-level transport layer protocol available and that other protocols such as User Datagram Protocol (UDP) may be used.
